The O2 firmware should allow any Simcard. Generally if you ask your service centre nicely they should be able to upgrade your phone with a generic firmware though it may cost you to have it done.
In any case, a SIM free, retail model will have no operator restrictions and will be able to run the generic/retail firmware for the model (and that's usually also out/released before any operator variants).
